3 Claims.

This invent1on relates to hinge-type joints, and more particularly to a joint formed of two longitudinal relatively pivotable hinge members specially constructed for fabrication by extrusion processes.

The advantages of low manufacturing costs and high quality product obtained in the fabrication of metallic articles by means of extrusion are too well-known to require elaboration. However, in order to utilize this mode of production, the articles must be of a configuration that permits of extrusion and it is usually quite difficult to devise a configuration and construction both capable of being extended and also durable and functionally efiicient.

It is therefore a primary object of the present invention to provide an inexpensive, strong and eflicient hinge-type joint formed of two relatively pivotable elements which are easily assembled and are ideally suited for fabrication by Wellknown extrusion processes. Other objects reside in the specific novel structural details of the joint, which details provide advantages in the manufacture, assembly and functioning of the joint.

Briefly described, the hinge joint embodying the present invention is formed of two segments having cylindrical hinge surfaces coaxially mounted, one within the other, and relatively pivotable about the common axis. A plurality of radial sections or projections extend inwardly from the outer cylindrically shaped hinge member in sliding contact with the outer cylindrical surface of the inner hinge member, and similarly, the latter inner member is provided with a plurality of radial projections extending outwardly and in sliding contact with the inner cylindrical surface of the outer hinge member, thereby providing for the relative pivotable mounting of the hinge members. The projections, of each hinge member coact with the projections of the other hinge member to provide a stop or abutment limiting the relative pivotal movement of the hinge members. Both hinge members may in another modification be integrally provided on their interior surfaces with radial portions extending inwardly and forming at their inner ends coacting ball and socket bearing elements.

The hinge-type joint of the present invention may be utilized in the construction of awnings, shutters, or in any other application where two members are to be pivotally secured with respect to each other.

It is to be understood that the specific embodiments of the invention shown in the drawing and described herein are merely illustrative of two of the many forms which the invention may take in practice, and are not to limit the scope of the invention, which is delineated in the appended claims.

In the drawings:

Fig. 1 is a perspective view of one form of the hinge-type joint;

Fig. 2 is a transverse sectional view of the embodiment of the invention illustrated in Fig. 1, the second pivotable member thereof being shown in a different position; and

Fig. 3 is a transverse sectional view of a second and preferred form of the invention.

Referring now to Figures 1 and 2 of the drawing, wherein is illustrated one form or modification of the invention, the reference numeral ll indicates generally a flat or planar member having along one longitudinal edge II a bracket or plate [2 integral therewith and extending perpendicular thereto. The bracket [2 is provided with apertures [3 or other suitable means for fixedly securing the member II to a frame, window sash, shutter, or any other type of structural element. The opposite longitudinal edge ll" of the planar member II has integrally formed therewith a pair of spaced arcuate oppositely disposed portions l4, [5. The latter are curved about a longitudinal axis, indicated at [6, so as to form a segment having a cylindrical hinge member l1 extending along the longitudinal edge ll of the planar member H.

A second flat or planar member I8 is provided and is adapted to be secured by any suitable means to another structural element (not shown) which is to be pivotally secured by means of the invention to the element on which the bracket I2 is mounted. A section I! is integral with the member I8 and extends perpendicularly therefrom toward the axis I6. A pair of spaced 0ppositely disposed arcuate portions 20, 2| are formed integral with the inner edge of the section l9. The arcuate portions 20, 2| are curved about the longitudinal axis It so as to form a second segment having a cylindrical hinge member 22 within the hinge member I'l.

As will be evident from Fig. 2, the hinge members I1 and 22 are coaxial or concentric about the axis I6. The outer cylindrical surface 23 of the inner hinge member 22 is spaced radially inwardly from the inner cylindrical surface 24 of the outer hinge member ll. The edges of the arcuate portions 26 and 2| form the interior of hinge member 22 and are provided with integral sections or projections 25, 26 extending outwardly toward and in substantial abutting contact with the inner cylindrical surface 24 of the outer hinge member ll. Sections or projections 21, 28 are similarly integral with the edges of the arcuate portions I4 and I5 form the outer hinge member I! and extend inwardly into contact with the outer cylindrical surface 23 of the inner hinge member 22. The inner surface 24 of outer hinge member I1 is also provided with an integral projection 29 extending radially inwardly toward the axis it.

The contact between the ends of the projections 25, 26, 21, 28 and the respective cylindrical surfaces 23, 24 is of a sliding nature so as to act as a bearing means for rotatably mounting the hingemembers I? and 22 for-relativepivotal movement: about the longitudinaraxis IS. The projections 25, 25, 21, and 28 also coact with the section l9 and projection 29 so as to limit the relative pivotal movement of hinge members ll,

22 in either direction of rotation. Referring:

to Fig. 2, wherein is shown one extreme relative position of the hinge members ll, 22, it'wilT'be seen that projection 28 is' abutting section l9,'.

projection 29 is abutting projection 25, and projection 2! is abutting projecti'on=-25 so as toprevent continued clockwise rotation of the inner hinge member 22 with respect to the outer hinge member H. The inner hinge member 22 may be pivoted counter-clockwise" with respectto -the outer "hinge member ll until "the otherextreme limiting positionis reached, when section It abuts projection 2?, projection 26 abuts projection 29 and projection abuts'projection 233.

It will. be understood that the entire structure shown in section in Fig. 2 extends longitudinally of and-parallel to the'axis- Itso as to provide an elongated hinge type joint consisting of two relatively pivotal integral members each having across-section uniform throughout its length so" as to be capable of being fabricated by an extrusion process; The two integral members 01' segments; each having a cylindrical hinge member-anda planar member, may be'quickiy and easily assembled by merely sliding the inner hinge member 22 into the outer hinge member ll.

Referring now-to Fig. 3, wherein is shown preferred form of the invention, the reference numerals El, 52 indicate two planar members equivalent to members ll, described modiiication of Figs. 1 audit. A- lo-ngitudinal' cylindrical hinge member isintegrally formed along each' of the longitudinal edges F, 52 of planar members ii, 52, the two hinge members-being indicated at 53 and 5d respecti velys The hinge-member 53 is formed of two spaced oppositely-disposed arcuate portions 55, 5B curved about a longitudinal axis indicated at 5i. The hingemember 54 isalso provided with'similar arcuateportions58, 55 curved about the axisfi'i and extending around the arcuate portions 551, fis whereby'the outer hinge member 54 is coaxialwith and partially encloses the inner hinge member 53.

The inner cylindrical surface Gil of :the outer hinge member-5 2' is spacedradially outwardly from the outer cylindrical .surface of the inner hinge member 53. The arcuate portions 55, 56

ofthe latterare integrally provided at their edges i with sections or projections 62, 63 extending outw'ardly toward and into abutting contactwith the inner cylindrical surface of'the outer hinge member 54 and the arcuate portions 58, 5d of the latter are similarly provided with sections or projections (54,55 extending inwardly and into abutting contact with the exterior cylindrical surface 6f of the inner hinge member 53. The projections 62, 55, 54, 65*are slidable with respect to the surfaces 66, iii wherebythetwo hinge members 53, 54 are relatively rotatable about the common axis 5 l'.

The-interiorcylindrical surface 56 of the inner hinge member 53 has integral therewith a radial portion 67 extending inwardly toward the-axis 5'1. The inner edge of the radial portion'fil is provided with a cylindrically shaped bearing 68 coaxial with the hinge members 53, 54. The interior surface 56- of-the outer hinge-member 54 has integral therewith a-second radial portion 69 extending inwardly toward the axis- 51. The inner edgeof the radial portiorr' 69 has-a longitudinal rounded rib or male bearing element IE1 rotatably mounted: within the cylirldrically shaped bearing 68. It will thus be obvious that the bearing 68 and rounded rib 10 coact to provide a bearing means additional to projections 62, 63, 64, 65 and surfaces 60, 6| for mounting the hinge members 53, 54 for relative pivotal movement.

The radial portion 69 is adapted to abut against the projections 62, 63 and the planar member 5| and projectionsM, 65 may also abut so as to limit the relative pivotal movement of the hinge members 53, 54. It will be understood that the sections shown in Fig. 3 are uniform and constant throughout the length of the joint so as to provide two integral longitudinal parts adapted-to be fabricated by extrusion and assembled by-sliding'the inner hinge member 53 into-and'longitudinally of the outer hinge member 54.
